LSC 606 Executive Summary E McLean

"Semantic" interoperability is based on a precise and correct use of the formal RDF semantics embodied in the RDF graph data model and in RDF-based vocabularies such as DCMI Metadata Terms. Semantics…refers to formally stated relationships between terms and rules for using such statements to draw automatic conclusions (logical inference)s”.
